Mixed Money counters have the ability to sort and count different denominations. Some have one pocket, while others have two. With one pocket mixed money counters, when there is an error or a counterfeit note detection, the machine is halted and you must remove the note. With two pocket counters, all counterfeit notes or error notes are rejected into the second pocket and counting continues. Most mixed money counters have counterfeit detection, including UV, IR and MG. All of our machines have a warranty period, so shop with confidence!
